Samuel fas gzzr ATT ORNEY Patented July 19, 1932 PATENT OFFICE SAMUEL JASGUR, OF BROOKLYN, NEW YORK WINDOW SHADE ADJUSTING DEVICE Application filed July 21,

My invention relates to adjustable window shades and refers particularly to devices adapted for the raising and lowering of window shades or curtains.

The rollers carrying window shades, or curtains, are usually attached to opposite sides of a window frame and hence are not capable of being raised or lowered.

- This fixed position of the curtain roller is objectionable as the unrolled curtain prevents the free access of air when the upper sash is lowered, and as it is frequently desirable to obtain free access of air through V the upper open portion of the window, while using the curtain as a screen only for the unopen portion, it is evident that a device which will accomplish this result is of great value and convenience.

v The device of my invention produces this desirable result in an eflective manner as will be evident upon a consideration of my specification and its accompanying drawings.

In the accompanying drawings illustrating one form of the devices of my invention, similar parts are designated by similar numerals.

' Figure 1 is a front view of one form of my device attached to a window frame.

Figure 2 is an enlarged section through the line 2'2 of Figure 1.

1981. Serial No. 552,200.

Figure 12 is a section on the line 1212 of Figure 11.

Figure 13 is a section through the-line 13-13 of Figure 11.

Figure 14 is a longitudinal detail of the curtain carrier of Figure 11.

In the accompanying drawings Figures 1 to 10 inclusive, illustrating one form of the device of my invention in operative position, I show a window frame having the bottom 20, the sides 21 and 22, the top 23 and carrying the upper sash 24- and the lower sash 25.

One of the elements of my device is a channel-shaped member having the base 26, a side 27 and a side 28 narrower than side 27 said channel-shaped member being attached to the inner face of the window frame top by screws passing through the angularly positioned head 29 of the channel-shaped member and to the inner face of the window frame side 21 by means of screws passing through the extended foot member 30, the side 28 of the channel-shaped member being thus spaced from the frame side 21.

My curtain carrier is of such construction that it is capable of longitudinal movement along the channel-shaped member, or support, but is prevented from transverse movement thereon, and has the side 31 abuttable upon the inner face of the channel-side 28, the member 32 abuttable upon the edge of the side 28, the side 33 abuttable upon the outer face of the channel side 28 and a plurality of extended members 34, 34, abuttable upon the outer face of the base 26 of the channel-shaped member. The side 31 has a plurality of hooks 35, 35, for purposes described later and flat lugs 36, 36, extend outwardly. at right angles from the side 33, each lug having an annular opening 37 therein. The upper portion of the device carries an arm 38 extending at right angles to the lugs 36, 36. The device also carries an extended arm 39 from which draperies or window hangings may be suspended from the 9 drapery rod 50.

A similar curtain carrier is attached to the inner face of the window frame side 22 and is shown in Figure 8, the several parts being designated by prime numerals. In this side member, however, the holes 37 37 of Figure 7 are replaced by downwardly extended lower sprocket 40 and an upper sprocket 41, a chain 42 meshing with the sprocket, the ends of the chain 42 beingattached to the two hooks 35, 35. Cords 43 and 44 are attached to the chain 42.

A similar arrangement of sprockets and chain is positioned within the channel-shaped member attached to the inner face of the window frame side 22, and the elements are indicated by prime numerals.

The two upper sprockets 41 and 41 are fixedly attached to the octagonal revoluble shaft 45 which enters octagonal openings in said sprockets.

A spring-roll curtain 47 is positioned within the lug openings 37 and 37.

It will thus be seen that if the cord 43 is pulled downwardly, the chain 42 will move, revolving the sprockets 40 and 41, the shaft 45 and the sprockets 40 and 41, thus moving the curtain evenly upwardly. A downward movement of the cord 44 will reverse the movement of these elements, moving the curtain downwardly.

The arm 38 will prevent the curtain stick 48from passino through the device thus preventing a complete unwinding of the curtain spring. 7

The bolt 46 which is capable of being inserted between the teeth of the sprocket 40 will maintain the curtain in any desired position'.

In order to prevent the free end of the curtain 47 from flapping when the window is open, I employ a metallic member 51 into which the curtain rod 52 is inserted and covered by the curtain 47. The member 51 is extended into the hook-shaped member 53 whichpasses between the narrow side 28 of the channel-shaped member and the window' frame. A device of this construction is carried by each end portion of the curtain rod 52. x

p In Figures 12 to 14 inclusive my device is shown as attached tothe front faces of the window frame instead of to the inner faces of the frame as previously described.

In this modified form of curtain carrier the curtain holding lugs 60, 60, are extended at right angles to the lugs 36, 36, in order that the openings 37 and 37 may receive a spring curtain roller.

In order to produce a co-ordinated movement of two chains 42 and 42, I provide the two upper sprockets 41 and 41 with a shaft 61 and 61 respectively to which are fixedly attached the two sprockets 62 and 62. A crossed chain 63 connects the two sprockets 62 and 62, Y

In this modification I have replaced the two cords shown in the first describedform of my device by extending the shaft 64 of the sprocket 40 through the channel-shaped member and attaching 'a handle 65 thereto, the revolution of which will operate the de- Vice. 1

It will thus be seen that my device presents an effective and inexpensive means for raising and lowering a curtain roller, with window draperies, if desired, among its other advantages being that the operating sprocket mechanism is practically completely enclosed,thus protecting it from dust and dirt, the ease of attachment to the window frame and the simplicity of its operation.

I do not limit myself to the particular size, shape, number or arrangement of parts as shown and described as these are given simply as a means for clearly describing the de vice of my invention.

What I claim is 1. In a device of the character described, in combination, a vertical channel-shaped. guide, the base of said guide being opened inwardly toward a window frame, one side of said guide being narrower than the other side and spaced from said window frame and a curtain-carrier extending through the space between the narrow sideof the guide and the window frame, allowing longitudinal movement of said carrier along said guide and preventing transverse movement thereof.

2. In a device of the character described, in combination, a vertical channel-shaped guide, the base of said guide being opened inwardly toward'a window frame, one side of said guide being narrower than the other side and'spa-ced from said window frame; and a curtain-carrier extending through the space between the narrow side of the guide and the window frame, abutting upon both faces of said narrow side, allowing longitudinal movement of said carrier along said guide and preventing transverse movement thereof.

Signed at New York city, in the county of New York and State of New York, this 14th day of July, 1931.
